Maintenance Model

According to a detailed study of the fault tree model of the flight control system about Boeing 777, a pre-program was established for the fault tree. The minimal cut sets of the treetops event was calculated by Fussell-Vesely algorithm. And the directed graph search process based on DFS and fault tree module searching method based on double DFLM was used to achieve modular decomposition of fault tree. Therefore, a better structure tree and better rules generate. Finally, it combines the fault tree fault model with the ARINC624 specification to achieve communication requirements between the central maintenance system and flight control system. The Boeing 777 maintenance model was realized.

Maintenance Model

For the maintenance problem of intelligent series system with buffer stock, a preventive maintenance model based on the threestage time delay theory is proposed. Firstly, the intelligent series system is decomposed into n − 1 virtual series systems by using approximate decomposition method. The impact factor is introduced to establish the failure rate and maintenance rate model of each virtual machine. Secondly, a preventive maintenance model based on the three-stage time delay theory is proposed for each virtual series system. The machine state from normal operation to failure stage is divided into three steps: initial defect, serious defect, and fault, and different distribution functions are defined in different stages to simulate the degradation process of the machine. Based on the three-stage time delay theory, the machine cost ratio model was established by taking the machine monitoring time and buffer stock as decision variables and the minimum unit time cost rate as objective function. Finally, the rationality and validity of the model are verified by an example analysis, which provides a basis for the maintenance of the intelligent series system.
